Wen you pour half a cup of cold water into half a cup of warm water, does the cold water sink or float?

Answer 1

The cold water sinks, because heat rises.

However, ice cubes float, so figure that one out.


When water freezes, it becomes less dense, unlike other elements or compounds. This is the reason why ice cubes float.

Answer 2

The cold water sinks because it is denser than the warm water. In general cold things are more dense than their warmer counterparts. Think of a hot air balloon for example.

One exception is when water freezes. Because of the crystalline structure of ice, solid ice is less dense than water, and so it floats (a good thing, or else the oceans would freeze from the bottom up, and the poor fish would be in trouble ... the oceans would probably freeze solid at the poles as well).

Answer 3

The cold water sinks, and the hot water rises.

Answer 4

The cold water sinks.

Answer 5

if you stir it the molecules exchange heat and all become uniform temperature with time. But as per some law i guess in physics "hot air rises" and the same applies to all fluids. So the hot water should be closer to the surface than the cold one.
until exchanging heat meaks them (molecules ) have the same temperature.

Answer 6

sink have you ever jumped into a pool or lake and the top layer is warm and bottom layer cold same with air heat rises.

Answer 7

cold sinks and hot rises

Answer 8

I believe hot rises
